About

The SCHOTT TEC TO package is a newly developed transistor outline (TO) which is ideal for laser diodes that require a thermoelectric cooler (TEC). The thermoelectric cooler allows for controlled heat dissipation, which leads to regulated and stable laser wavelengths and higher power signal transmission.

DML TEC TO for single-channel DWDM in 25G CPRI, XGPON OLT Tx and other tunable laser applications.

Product features

  • Designed for 25G DFB laser (on TEC).
  • Includes submount with 25ohm impedance G-S-G-S-G traces capable of 25 GBit/s.
  • Asymmetric design for mass producibility at affordable prices.
  • Potential application in XGPON.
